PAUL JULIUS LAMPL, OF WIESBADEN, GERMANY.

SPECIFICATION forming part of Letters Patent No. 765,365, dated July 19, 1904.

Application filed September 23, 1902. Serial No. 124,541. (No model.)

To JZ whom, it may concern:

Beit known that I, PAUL JULIUs LAMPL, a subject of the Emperor of Germany, residing at Viesbaden, in the Province of Hesse-Nas-v ject of the invention is to provide an apparatus by which a printer may easily and without special knowledge easily reproduce from any ordinary type-set material, such as'words, ornamental printing, and the like.

rlhe invention is illustrated in the accom-` panying drawings, in which- Figure 1 is a plan view with parts rbroken away and parts removed. Fig. 2 is a central longitudinal vertical section. Fig. 3 is a transverse section with the types represented as in inverted position. Fig. A is an end view looking from the left of- Fig. 2. Fig. 5 is a detail view showing one of the blocks used for filling purposes. Fig. 6 is a view similar -to Fig. 1, but showing a modified form. Eig. 7 is a longitudinal sectional view. Figs. 8 and 9 are transverse sectional views, and Fig. 10 is an end view looking from the right of Eig.- 6.

Referring by reference characters to these i figures, it will be seen that the device includes two side pieces a b, which are rigidly though detach ably connected together by an end plate c, secured to the plates a b, preferably by set-screws, as shown. The opposite edges lof the plates a ZJ are rabbeted, as indicated more clearly in Fig. 3, to Vform seats to receive the edges of the face-plates t 2'.. These plates are held removably on the seats and are adapted to be held in position during the. casting operation by cross bars or arms g,V

pivotally connect-ed by means of screws, as shown, to one of the side plates, as b, and having' recess portions f, adapted to be engaged with and disengaged from corresponding screws j", carried by the plate a. A setscrew /c passes through the end plate c and `cessed to formthe sprue-hole.

has a swiveled connection at its inner end with a movable wall or follower e, a screw being provided at its outer end with a suitable head or handle. ln the opposite end o f the device is located a block or blocks d, re-

It will be noticed that the smaller end of this sprue-hole is located nearer to the plate /L than it is to the plate c'. i

At m, Fig. 5, I have shown an enlarged view of one of the filling-blocks, which are shown in position in Figs. l and 2. 1n order to guide the follower e more eifectually and hold it in proper alinement, I provide rods Z, which are secured to firmly-extended portions of the follower and passing through suitable openings in the end plate c.

In the form shown in Figs. 6 to 10, both inclusive, owing` to the increased length of the device I prefer to provide two set-screws 7n for the follower and but a single guide-rod Z, and it is desirablein this form to provide an additional set of clamping arms or bars g betweenV the others, as indicated in Fig. 7. As this form is in other respects substantially the same, further and more detailed dev and end d or in the corner formed by side and end d, supposing that the set material does n ot occupy the entire space within the casting device. The spacing-blocks m are then placed alongside of the free side edge of the type-set material. The follower is moved up to clamp the material and the blocks m rigidly in position. vIt will thus be seen that a space is provided above the face of the type-set material, which is bounded, say, by the wall a, which is back of the type-set material, the inner face of the block d, the face of the blocks m, and the inner face ofthe follower. rlhis space over the type-set material is then filled up slightly above the side walls thereofwith a proper molding material, such as gypsum or the like, wand after the mass has become hard all the material which projects above the side walls is removed. The formed matrix and the type-set material are then removed from the apparatus, and instead or' the typeset material the matrix is again replaced with its face pointing upward. The apparatus is then adjusted in the same manner as before, and finally plate z' is applied in place and the apparatus is ready to receive the casting. This of course is done by supporting the apparatus in a vertical position w-ith the spruehole uppermost and pouring in the casting material. In order to take the casting out of the apparatus, it is placed with the facingplate 't' downward. The plate z is then removed, and as the matrix rests on top of the casting it may be easily removed without damage after the set-screw and the inserted pieces m and a have been loosened.

Having thus described my invention, what I claim is- 1. Forming and casting apparatus for reproducing type-set material comprising a rigid frame with movable facing-walls and inserted pieces and having a sprue-hole located in one end and in a plane nearer to one facing-wall than the other, substantially as described.

2. A forming and casting apparatus for the reproduction of type-set material comprising a rigid frame with side walls and inserted pieces, top and bottom facing walls or plates, and means for securing said plates removably in position, substantially as described.

3. In combination, the rigid frame, a movable partition, removable spacing-blocks, removable top and bottom plates and means closing the open end oi' the frame, said means having a sprue hole or opening located to one side of the central plane of the frame.

4. In combination, the side plates, the end plates rigidly connecting the same, the facingplates situated in rabbets in the edges of the side plates, locking arms and screws for holding said facing-plates in place, and a follower conned between said side facing-plates, and an operating-screw connected with said follower and passing through the end plate, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

PAUL JULIUS LAMPL.
